## Product Overview: CSBFB700KJ58-R1 The **CSBFB700KJ58-R1** is a specific electronic component manufactured by **Murata Electronics**. It belongs to the **Ceramic Resonator** family, specifically the **CERALOCK®** line. These components are used to generate stable clock signals for microprocessors and microcontrollers. --- ### Technical Specifications | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Murata Electronics | | **Series** | CERALOCK® CSBFB | | **Frequency** | 700 kHz | | **Frequency Tolerance** | ±0.5% | | **Resonant Impedance** | 50 Ω (Max) | | **Operating Temperature** | -20°C to +80°C | | **Mounting Type** | Surface Mount (SMD) | | **Package / Case** | 2-SMD, Non-Standard | | **Dimensions** | 5.00mm L x 4.10mm W | --- ### Key Features and Functionality The CSBFB series is designed for low-frequency applications. Below are the primary characteristics of this part: 1. **Ceramic Material:** Unlike quartz crystals, these use piezoelectric ceramics. They are generally more robust and have faster "start-up" times than traditional crystals. 2. **Built-in Load Capacitors:** While some ceramic resonators require external capacitors to complete the oscillation circuit, many in this series are designed for simplified integration, though you should verify the specific circuit diagram in the datasheet for the "KJ58" suffix variations. 3. **Low Profile:** The SMD design allows for high-density mounting on printed circuit boards (PCBs), making it ideal for compact consumer electronics. 4. **Frequency Range:** At **700 kHz**, this is a "low-frequency" resonator, often used in specialized communication protocols or older legacy timing circuits. --- ### Common Applications * **Remote Controls:** Used in infrared (IR) transmission timing. * **Microcontrollers:** Provides the system clock for low-speed 8-bit or 16-bit MCUs. * **Household Appliances:** Clocking for washing machines, microwave timers, or dishwashers. * **Audio Equipment:** Basic timing for digital signal processing in consumer audio. --- ### Typical Circuit Connection The component typically interfaces with an inverter stage (inside a microcontroller) as follows: ```mermaid graph LR A[MCU Pin: OSC_IN] --- B[Ceramic Resonator] B --- C[MCU Pin: OSC_OUT] B --- D[Ground] ``` ---
